Metairie-based Louisiana Bancorp Inc.’s second-quarter profit inched upward to $552,000, or 20 cents per share, compared to $519,000, or 20 cents per share, a year ago.

Louisiana Bancorp is the holding company for Bank of New Orleans.

Although net interest income jumped $325,000 to $2.8 million for the quarter, those gains were largely offset by higher non-interest expenses. The costs included legal and investment banking fees related to Lafayette-based Home Bancorp’s proposed $74.5 million acquisition of Louisiana Bancorp.
